As we observe paranormal activity in our ITC devices and software, the grand question is how is this happening?
In quantum mechanics, the vacuum is not actually empty. It is filled with particle-antiparticle pairs that perpetually go in and out of existence. The lifetime, t, of these pairs is governed by the Heisenberg uncertainty principle:
Despite my careless description of a physical concept, it should be noted, no one really knows the density of virtual particle pairs in the vacuum. If the density were infinite, the universe would collapse under the weight of gravity. If it were finite and not too small, could we someday tap into it to get free energy?
In any case, when we use a device to tap into this field, we are not going to get a whole lot out, unless the device is receptive to a large bandwidth of energies (from radio to light).
What would a vacuum photon look like? Likely, a very very short pulse of energy, maybe a femtosecond or picosecond. I like to call these hypothetical pulses "spiritons," but the reality is that observed random pulses of energy could be just that, random, and not caused by the communication intentions of a spirit / interdimensional entity.
A hot topic in the quantum science community, recently, is the idea of quantum selection (also Google "quantum eraser") - that is, the effect of the researcher on the outcome of quantum-level experiments. It's driving some researchers mad, but in our case, we ask a similar but crazier question: "what if spirits can select / collapse quantum states?" If so, the best devices would be ones where many quantum states are prepared and metastable (barely stable) until a spirit decides which way they will go. Presumably, we want to continuously and quickly prepare non-equlibrium, metastable states for spirits to collapse at a desired rate of information (i.e., bits per second).
Imagine a system that we could create preparing a metastable state 10 million times a second: a spirit could either leave the state alone, or select "up" or "down." This would allow information transfer of 10 megabits / second. Not bad? Of course, we would need to make sure that nothing else collapses our states like thermal, electrical energy, our own thoughts (?!?). No problem: we could shield the system from all known fields (e.g., magnetic) and put it in a near-zero Kelvin liquid helium-cooled freezer.
In reality, until our research becomes "mainstream," liquid helium-cooled experiments are not likely. Indeed, I had a vision once of seeing an advanced video device that seemed to have it's own internal sub-freezing (< 0 Celsius) cooling system. It had the brand name, Moen, I imagine in reverence to the famous afterlife pioneer, Bruce Moen. However, for now, we are limited to room temperature or at best liquid nitrogen-cooled (77 K) systems.
With the remaining thermal energy, how can we detect the presumably weak signal from spirit?
One idea is microscopic isolation - also out of the range of our non-mainstream research labs. Researchers think that nitrogen atom "vacancies" in diamond, if sufficiently spaced apart, could act as isolated qubits. These qubits, if put into a metastable state, could be allowed to collapse into an "up" or "down" state and then read with a sensitive detector. Perhaps the spirits can manipulate these miniature "abacuses" for us to read their messages?
One "hot" area of research is the use of lasers to obtain quantum noise. The idea is that beam splitters have a 50/50 chance of sending a photon one direction or another. With a suitable setup, one can count the photons going in each direction as a function of time.
The noise present in many electronic devices, for now, offers our best chance at sampling quantum effects. Yes, the noise will be dominated by thermal motions, but if enough spirit signal can be collected, we may be able to infer the rest using tools like machine learning.
One idea, is to have many noise sources in an array. The concept is that if each noise source has independent, non-correlated fluctuations, when we sum up the signals, the spirit (quantum) signal might become more pronounced. The theory says that signal-to-noise ratio could increase by as much as the square root of N, where N is the number of detectors.
The reality is that this improvement in arrays hasn't been realized in my experiments. Perhaps, the noise in each device isn't uncorrelated like we hope? Or maybe, the spirit signal is not equally imprinted on all of the devices at once?
The take home message is that given our current affordable device options, spirit influence is a tiny portion of the overall noise (entropy). Incidentally, a spirit once suggested to me in an astral projection, the proportion is 1 in 500! Any method we can dream up of to improve the ratio of spirit-to-noise will lead to improved ITC.
